Christmas Projects

A very interesting musical Christmas decoration light circuit can be built using a single IC, and some other few passive components, let’s learn the details as furnished below. By: Ritu Panday How the Circuit Works The circuit of a selectable muti-musical song player with 5 sequential light pattern generator is discussed here using just Read More

A simple mains operated, transformerless 8 function Christmas light circuit can be made by using a single IC, a rotary switch and a few SCRs, let’s learn the procedures in detail. The circuit is based on a single chip UTC8156 which is internally preprogrammed to produce 8 unique selectable light effects across 4 numbers of Read More

The post discuses a sequentially advancing 25 LED timer circuit which may be initiated on the 1st day of December so that each LeD lights up on each day until the 25th of December (on Christmas) when all the 25 LeD can be seen lit up. The circuit was requested by Mr. Guy Mathews Technical Read More

The post explains a simple, compact, 220V, 120V transformerless light chaser circuit which can be used for illuminating mains operated lamps in a sequential chasing manner. Main Technical Features The chasing effect can be altered by means of pot controls. The system can be used as a decorative lighting during festive seasons like in Christmas Read More

The article discusses the construction details of the popular “knight rider” chaser circuit incorporating LEDs as well as mains operated bulbs through triacs. The proposed circuit is transformerless and is thus a lot compact and light weight. The Circuit Concept It’s basically a light chaser or a running light effect generator circuit, quite resembling the Read More

In the following article we will earn how to build a simple LED chaser circuit with a push pull or reverse forward sequencing effect, and also in the later part of the article we will learn how this simple LED chaser cold be upgraded to a 200 LED laser circuit with a reverse forward LED Read More
